What is a Fiber City?


The Farmington Area FiberCity® is more than just a superfast fiber internet connection to homes and businesses. It will futureproof the area for generations to come, bring you more choice of providers, boost its economy and enable Smart City applications to make for a great city to live, work and play.

The Farmington Area FiberCity® is being built citywide, meaning we pass each and every home and business, enabling every household opportunity to connect, helping to close the digital divide.

Each FiberCity® is based on a templated design, where each build is scaled replica of SiFi’s standard architecture. Each FiberCity®’s intra-city network operates independently and is standalone from other FiberCities®, apart from provisioning systems and monitoring and control, which is managed centrally. The passive network consists of a buried, passive duct network.

This duct network is designed to accommodate pneumatically blown fiber. It typically passes all addresses within a city, along with the provision for Smart City Points for future connected infrastructure. The active network consists of an MPLS (Multiprotocol Label Switching) core of distributed, active street cabinets and aggregation shelters (huts) in each city, and an edge with PON (Passive Optical Network) connections from street-side cabinets to individual premises.

Network Design

This diagram illustrates the duct design components and hierarchy of types for a hypothetical city with the Metro network shown in green, the Feeder network in orange and the Distribution network in blue.

• The Metro Network (green) connects Cabinets to Huts.

• The Feeder Network (yellow) connects distribution chambers to Cabinets.

• The Distribution Network (blue) connects Demand Points to Distribution Chambers. Whilst not shown in the attached diagram, each Hut connects back to two separate data center locations.
